Is it possible to add an LOV behind the Value field on a Value Set?

Summary:

Hi Community,

Our customer is looking forward to create a table of important setup for them inside a value set. This table stores specific codes for cities and postal codes, but it requires some validations, therefore it is not good to use Manage Geographies for it, but we are exploring the possibility of a value set.

1- We have created the value set and added columns to it via value set values FF —> FND_VS_VALUES_B.

2- However, we wanted to include in values a LOV list, instead of being a free text, as we want to use it's Unique Key capability —>
